"It keeps happening"? What else is going on then?

Most of the time "praying" is not going to work simply because there are right and wrong ways to pray. Asking God to protect you isn't going to work because He already has shown us in the Bible how to act against spirits

Is there any reason you can think of that this spirit might have a right in your home or bedroom?
